Coating each hair in hydrolysed keratin helps smooth the cuticle, so brows look smoother, more defined and better groomed over repeated use. Biotin — a B-vitamin (B7) commonly associated with hair and nail condition. In this formula it supports the appearance of fuller-looking, healthier-looking brows by conditioning the existing hair. Peptides — short chains of amino acids that are listed among the ingredients in this cosmetic brow-conditioning formula. Not inside: no prostaglandin analogues (the class of ingredient used in prescription-style lash serums), no parabens — a cosmetic, condition-based approach rather than a hormonal one. What to expect With regular use, the serum helps condition existing brow hairs for a softer, more groomed appearance. Individual results vary. FAQ What can I expect? The serum helps condition existing brow hairs for a softer, more groomed appearance. Apply to clean, dry brows and brush through with the spoolie. Individual experiences vary. Will it help over-plucked brows? The serum conditions existing brow hairs and supports a fuller-looking appearance. It cannot replace missing brow hairs. Can I wear makeup over it? Apply to clean, dry brows. Allow the serum to dry fully before applying brow makeup. Can I use it after microblading? Follow your microblading artist’s aftercare instructions and do not apply the serum to skin that is still healing. Ask your artist or healthcare professional when to resume brow products. Is it the same as the lash serum? Same philosophy, different build: the brow formula and applicator are designed for skin coverage along the brow line. How much is in one tube? Each tube contains 5 mL of serum. Apply as directed. What if I have sensitive skin? Individual sensitivities vary. Patch test before first use and discontinue use if irritation occurs. Can men use it too? Yes — the formula and application are the same regardless of gender; it's simply a brow-conditioning serum. Do I need to stop using it once I see results? Continue using the serum as directed if it suits your routine. It conditions existing brow hairs; appearance can vary between people, and lasting results are not guaranteed. How is this different from brow serums that contain prostaglandins? Our published ingredient list contains no prostaglandin analogues. This formula is intended for cosmetic conditioning of existing brow hairs, not to change hair growth. Can I use it if I'm pregnant or breastfeeding? As a general precaution with any cosmetic active, ask your doctor or pharmacist before starting a new product while pregnant or breastfeeding. Will it interfere with brow tinting? Do not assume compatibility with brow tinting products or freshly treated skin. Follow your tinting professional's aftercare instructions and ask when to resume brow serum.
